• Certified High Speed USB
• Most successful interface standard, about 3
  billion ports
• 480 MBit data rates
• Certified Wireless USB
• High speed USB replacement (480 MBits/s), Any
  other questions?
• Based on WiMedia Alliance OFDM UWB Technology
• Not just wireless USB (low speed mice and
  keyboards)
• Low power, short range, high data rates
• Bluetooth
• Headsets, the current killer application (1
  MBit/s)
• Bluetooth now planning to use WiMedia UWB for
  higher data rates
• Years away, must find an application space

UWB is sometimes called an underlay technology,
because it can transmit in the noise floor of
narrow band signals. More BW translates to higher
data rates even with simple modulation techniques
